    Shear Stress and Head Fasteners

    Well, I have not brushed up on my materials and statics courses, But I was thinking about this the other day. . .Most would assume that the shear stress applied to a head fastener such as L19 or typical ARP head studs is quite miniscule. And I agree.But considering the higher the carbon...

    2g head intake ports vs. 4g61T head intake ports

    Can some one confirm that 2g head intake ports are identical in shape as 4g61T head intake ports? With their eyes in the port would be fine, but not just the mouth (inlet) dimensions.

    All motor w/ same Power AND Cost as a Turbo Swap: Modding the front of the 4g64

    The 7bolt 4g64 is like a 7bolt 2g motor. This 4g64 cam out of a 1995 galant ls. The original driverside motor mount is more like a 2g mount than 1g mount. To mount this motor in a 1g chassis you must use the 1g timing belt idler & tensioner pulley base/assembly which includes the right...

    4g61 cam gears: 4g61 has shorter deck & 4g64 has taller deck vs. 4g63 . . .

    I've never gotten a direct or reliable answer on this. . .Since a 4g64 has a 6mm taller deck than a 4g63 and a 4g61 has a 6mm shorter deck than a 4g63, is it possible that the 4g61 cam gears are aligned like the dohc 4g64 cam gears? And can be used on a 4g64/4g63-head combination????. ...

    All motor w/ same Power AND Cost as a Turbo Swap: Sexy poses of my n/a motor :)

    Some asked for more pics of the motor.What finally pushed me to do it was that my brother came over and said you need to do a photo shoot with this motor AS is. OK, so I did it. I have no where else to put these but here. Otherwise they get deleted. I'm really antisipating what the car will...

    Progress on 'All motor w/ same Power AND Cost as a Turbo Swap'

    Here's a bit of progress. . .First of all take a look at this thread on the elantra 1.6/1.8 head. As mentioned in the last thread, this head has a 43cc chamber. And I measured a 13mm width from chamber to chamber, vs. the stock 4g63 which has about 8mm width. :)I bought the 10 TTY 7bolt 4g63...

    Yes Wiseman with a newb question: 7bolt 4g64 vs. 7bolt 4g63 head bolts. Misticj look!

    . . .They are torque to yield for both. They torque at the same amount. Just wondering. Autozoo and un-Advance auto list 2.4 4g64 head bolts as unavailable. But the 7-bolt 2g headbolts they have even in stock. Am I a retard? Arn't 4g64 and 4g63 7bolt TTY headbolts the same thing?

    All motor w/ same Power AND Cost as a Turbo Swap

    My first dsm was a forest green 1992 Eclipse witha n/a 4g63. I loved that car. It was a beater and I beat it. I always wondered if I had htat car now what I could do with it.I could do a turbo swap to it, Likely I would have kept he stock pistons and just put the turbo ecu, injectors, and...

    AWD auto to manual swap. . . Can you use the automatic driveshaft?

    I've not seen a definate answer to this question.I'm swapping a 1Ga auto tranny out for a 5speed tranny for more beater fun. Can you use the automatic driveshaft? I see that the 5speed motormounts move the engine/tranny assembly to the firewall about 1/2 inch. . .

    Porting head: What to do about the "humps" in the exhaust port?

    What's under these humps at the bottem of the exhaust ports on the outside walls? water or oil passage? Do they serve some aerodynamic purpose? Has anyone done away with these? They look like they are just squeezing flow.The valve side of the hump is flat and smooth right into the valve...

    I'm bored and I have a minigrinder. Hmmm. . . . Head porting!!!

    Don't port your 16g.

    Here's a few pics of how I avoid hours of porting yet still eliminate that terrible "down-step" going from a 2g manifold to any 7cm^2 turbine housing (16g, 18g, 20g). It involves a piece of 2" galvanized pipe from Lowe's or home depot.A 2g manifold has a step in it. The outermost inside...

    FWD and A/T AWD maps are more aggresive?

Or is the Automatic AWD (e932a) and the FWD (e932) demonstrate a more aggressive A/F curve AND timing curve? For the E932A, the beginning address...

    It happens everytime I park the thing for longer than 4-5 days. It seems like the pads are rusting onto the rotors. I'll have to rev and drop the clutch to break them loose (w/ a loud report). Also, they seam to drag for a long time then free up. After every time it freezes up, when I bring the...

    Oil feed from filter housing for MHI turbo. Should I add a turbo oil filter?

    Well, the MHI 14b 16g turbos seam to do fine w/ a head fed oil line. So these turbos don't seam to need the astronomical oil pressures that other journal bearing turbos love.Considering many have plumbed from the filter housing and have had no ill effects, I thought that I'd try it. Cleaner...
